OVEN-SHELF.

' Specification of Letters Patent.

Patented Nov. 5, 1912.

Application filed December 18, 1911. Serial No. 666,526.

To all whom it may concern:

Be it known that I, LOTTIE M. AMsrAoHER, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, and State of Michigan, have invented certain new and useful Improvements in Oven-Shelves, of which the following is a specification.

This invention relates to improvements in oven shelves.

In the use of ovens of domestic stoves and ranges it is frequently found that one portion or side of the oven has greater heat than another portion or side so that articles placed therein are baked unevenly.

The main objects of this invention are,

first, to provide an improved oven shelf having grid or article support portions which may be revolved or turned to adjust the articles placed thereon. Second, to provide an oven shelf having these advantages which is simple and economical in structure, and very easily manipulated.

Further objects, and objects relating to the structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a plan view of a structure embodying the features of my invention. Fig. II is an inverted view of a structure shown in Fig. I with the shelf extension slides 16 extended. Fig. III is a rear elevation view with the shelf extension slides extended, and Fig. IV is a side view showing the arrangement of the extension slides 16, the grid supporting bar and grid actuating means being omitted.

In the drawing, similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, my improved oven shelf comprises a body 1 adapted as is customary to be supported by the shelf ledges in an oven.

The body 1 is provided with circular openings 2, which merge or open into each other at their inner sides.

The grids or article supports 3 are ar ranged in these openings with their upper surfaces flush with the upper surface of the body 1. These grids are revolubly mounted upon the supporting bar 4: which is arranged under the openings 2 to span the same. The bar 4 is secured at its ends to the under side of the body 1 as by means of the screws 5. The grids are revolubly mounted on the journals 6 carried by this bar. The grids are provided with peripheral teeth 7, the teeth being arranged in mesh as clearly illustrated so that when one grid is revolved, the other is turned in the opposite direction.

On the under side of one of the grids is a beveled gear 8. The bar 4 is offset at 9 to receive this gear 8. An adjusting shaft 10 provided with a hand wheel 11 at its outer end, is supported under the body 1 by the bearings 12 and 13. The bearing 12 is mounted on the'under side of the body 1 at the edge thereof, while the bearing 13 is mounted on the bar 4:. On the shaft 10, is the beveled gear 14, meshing with the beveled gear 8 of the grid. Thus arranged, when the adjusting shaft 10 is turned, both of the grids are revolved. The grids are further supported by the lug-like supports 15 on the under side of the body 1 which project under the edges of the grids as clearly shown in Fig. II. These supports assist materially in carrying the load on the grids and relieve the journals of twisting strains.

To adapt the shelf to ovens of different sizes, I preferably provide the body 1 with extension slides 16 which are arranged in grooves 17 on the under side of the body and secured by the screws 18 which engage longitudinal slots 19. These slides can be collapsed into the grooves 17 as shown in Fig. I or extended, as shown in Fig. II. This renders the shelf adaptable to ovens of different sizes.

I have illustrated and described my improvements in a simple embodiment.

I am aware that considerable structural variations are possible, but as such structural variations will undoubtedly be readily understood by those skilled in the art to which this invention relates, I have not attempted to illustrate or describe the same herein.

Having thus described my invention, what I claim is new and desire to secure by Letters Patent is:

1. An oven shelf, comprising a body having circular openings therein opening into each other; toothed grids arranged in said openings with their teeth in mesh, the upper surfaces of the grids being flush with the upper surface of the body, one of said grids being provided with. a beveled gear on its under side; a supporting bar on which said grids are revolubly mounted, arranged on the under side of said body, said bar being oifset downwardly to receive said gear of said grid; an adjusting shaft having a hand wheel at its outer end; bearings for said shaft, the bearing for the inner end of the shaft being arranged on said bar, the bearing for the outer end of said shaft being arranged on the under side of said body; a beveled gear on said shaft arranged in mesh with said gear on said grid; and supports on said body at the edges of said grid openings projecting under said grids.

2. An oven shelf, comprising a body having circular openings therein opening into each other; toothed gridsarranged in said openings with their teeth in mesh, the upper surfaces of the grids being flush with the upper surface of the body, one of said grids being provided with a beveled gear on its under side; a supporting bar on which said grids are revolubly mounted, arranged on the under side of said body, said bar being offset downwardly to receive said gear of said grid; an adjusting shaft having a hand wheel at its outer end; bearings for said shaft, the bearing for the inner end of the shaft being arrangedon said bar, the bearing for the outer end of said shaft being arranged on the under side of said body; and a beveled gear on said shaft arranged in mesh with said gear on said grid.

3. An oven shelf, comprising a body having an opening therein; grids having teeth thereon arranged in said opening with their teeth in mesh; a supporting bar on which said grids are revolubly mounted, arranged on the under side of said body; supports on said body at the edges of saidopening projecting under said grids; and means for adjusting said grids having driving connection with one of them. 7

4. An oven shelf, comprising a body having an opening therein; grids having teeth thereon arranged in said opening with their teeth in mesh; a supporting bar on which said grids are revolubly mounted, arranged on the under side of said body; and means for adjusting said grids having driving connection with one of them.

5. In an oven shelf, the combination with the body having laterally disposed grooves in its under side; longitudinally slotted extension; slides arranged in said grooves; and screws arranged in the slots of said slides whereby they are adjustably supported in said grooves.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses. I
